AA Battery Leakage After Long-Term Disuse
Professional Term:
- Electrolyte leakage
- Battery leakage
- More technically: Battery electrolyte leakage due to self-discharge and chemical decomposition
Causes:
- Zinc corrosion over time
- Gas buildup inside the battery
- Seal failure, leading to leakage
- Chemical degradation of the battery's internal components
Common Leakage Substance:
-
Potassium hydroxide (from alkaline batteries)
- A caustic and corrosive substance that can damage electronics and surfaces
Notes:
- Most common in alkaline and zinc-carbon AA batteries
- Happens especially when batteries are stored unused for extended periods
Prevention Tips:
- Remove batteries from unused devices
- Store batteries in a cool, dry place
- Use newer batteries with better sealing technology
